DESCRIPTION OF THE PREFERRED EMBODIMENT

Hereinafter, a preferred embodiment of the present invention will be explained in detail with reference to the accompanying drawings.

FIG. 1 is a schematic view showing a signal cable 6 connected to a monitor 1. As illustrated in FIG. 1, the monitor 1 has a front case 3, a cathode ray tube 2 mounted on the front case 3 for displaying a character or a picture, a rear case 7 integrally assembled to the back of the front case 3 for protecting interior accessories, a printed circuit board 4 (hereinafter, PCB) for electrically controlling the monitor 1, a bottom chassis (grounding member) 5 for securing the PCB 4 to the front case 3, and a signal cable 6 for transmitting a predetermined signal outputted from a computer(not shown) to the PCB 4.

The signal cable 6 comprises a holder 8 formed at a predetermined portion thereof for securing the signal cable 6 to the bottom chassis 5. That is, the holder 8 and the signal cable 6 are manufactured as one body by a molding process. The holder 8 comprises coupling recesses 20 formed downwardly at both side surfaces thereof.

Moreover, the bottom chassis 5 comprises a receiving groove 9 of a U-shape formed at a predetermined portion, more specifically, at the portion securing the signal cable 6 to the bottom chassis 5. Accordingly, the coupling recesses 20 of the holder 8 are received within and engaged with the receiving groove 9 of the bottom chassis 5 so that the signal cable 6 is secured to the bottom chassis 5.

On the other hand, in order to ground the signal cable 6, a cable shield 11 is formed with an ecdysis portion 13 at a predetermined portion thereof. After the ecdysis of the cable shield 11 is formed, a clamp 12 is mounted on the ecdysis portion 13 of the signal cable 6, and the clamp 12 is mounted on the bottom chassis 5 by using a screw(not shown) so as to ground the signal cable 6 to the bottom chassis 5. A contracting tube is inserted into the ecdysis portion (not shown in FIG. 1) of the signal cable 6 for preventing the signal cable 6 from shorting with other components.

However, the above grounding method is complicated. The ecdysis portion 13 is formed from an ecdysis of the cable shield 11, the clamp 12 wraps around the ecdysis portion 13, the clamp 12 is bolted to the bottom chassis 5 by a screw(not shown), and the contracting tube is inserted into the signal cable 6.

Therefore, as described above, the grounding process of the signal cable is carried out separately from the assembly process thereof by securing the cable to the bottom chassis 5.

Furthermore, since tools such as a screw or a clamp are required for grounding the signal cable, the manufacturing cost thereof is increased.

FIG. 2 is a partial enlarged perspective view showing the grounding apparatus of the signal cable according to the present invention;

FIGS. 3A, 3B and 3C are views showing an assembly sequence of the grounding apparatus of the signal cable according to the present invention; and

FIG. 4 is a side view showing a grounding state of the grounded apparatus of the signal cable according to the present invention.

Since the monitor associated with the grounding apparatus discussed below has the same structure as the monitor illustrated in FIG. 1, the explanation for the monitor will be omitted.

As illustrated in FIG. 4, a signal cable 6 comprises a holder 8 formed integrally at a predetermined position thereof for securing the signal cable 6 to the bottom chassis 5. The holder 8 is manufactured integrally with the signal cable 6 by a molding process, and comprises a downwardly extending coupling recess 20 at each side surface thereof.

As shown in FIG. 2, the grounding apparatus 30 comprises a grounding plate 34 inserted into the coupling recess 20 of FIG. 4, and a clamp 24 protruding from the grounding plate 34 so as to make contact with the ecdysis portion 23 (FIG. 3A) of the signal cable 6.

The grounding plate 34 has a first vertical portion 31 inserted into the coupling recess 20 (FIG. 3), a second vertical portion 33 located opposite to the first vertical portion 31 for making contact with one side surface of the holder 8, and a horizontal portion 32 integrally connecting the first and second vertical portions 31 and 33, respectively. Accordingly, the grounding apparatus 30 is secured to the holder 8 of the signal cable 6, and the holder 8 is inserted into the receiving groove 9 of the bottom chassis 5. At this point, the first vertical portion 31 makes contact with the bottom chassis 5 (FIG. 3) so as to be grounded.

The clamp 24 vertically protrudes from the second vertical portion 33 of the grounding plate 34. The clamp 24 wraps around the ecdysis portion 23 of the signal cable 6. Accordingly, the signal cable 6 is grounded on the bottom chassis 5 by the clamp 24 and the grounding plate 34.

On the other hand, a contracting tube 25 (FIG. 4) is mounted on the signal cable 6 so as to insulate the ecdysis portion 23 of the signal cable 6. Accordingly, the contracting tube 25 wraps around the clamp 24 and the ecdysis portion 23, and it is possible to prevent the ecdysis portion 23 of the signal cable 6 from shorting with other components. Moreover, the contracting tube 25 can be elongated until it reaches the clamp 24.

As described above, in order to secure the signal cable 6 to the bottom chassis 5, the holder 8 of the signal cable 6 is inserted into the receiving groove 9 of the bottom chassis 5 at the same time that the grounding of the signal cable 6 is carried out.

Hereinafter, the operation of the preferred embodiment according to the present invention will be explained in more detail.

As illustrated in FIG. 3A, one end of the signal cable 6 is connected to PCB 4. The signal cable 6 comprises the holder 8 formed at a predetermined position thereof for securing the signal cable 6 to the bottom chassis 5. The signal cable 6 comprises the ecdysis portion 23 for grounding purposes. At this point, the grounding apparatus 30 is mounted on the holder 8 in the direction of an arrow A in FIG. 3A.

FIG. 3B shows a state wherein the grounding apparatus 30 is mounted on the holder 8 of the signal cable 6. That is, the first vertical portion 31 of the grounding apparatus 30 is inserted into the coupling recess 20 of the holder 8, and the second vertical portion 33 makes contact with the one side surface 8a of the holder 8. The clamp 24 wraps around the ecdysis portion 23 of the signal cable 6.

As illustrated in FIG. 3C, after the grounding apparatus 30 is mounted on the holder 8, the clamp 24 is pressed by a tool so that the clamp 24 wraps around the ecdysis portion 23. The contracting tube 25 is inserted into the ecdysis portion 23 of the signal cable 6, thereby preventing the cable 6 from shorting with other components.

FIG. 4 is a side view showing a grounding state of the grounding apparatus 30 of the signal cable 6 according to the present invention. As illustrated therein, the holder 8 (on which the grounding apparatus 30 is mounted) is slidably inserted into the receiving groove 9 of the bottom chassis 5. Accordingly, as a result the coupling recess 20 of the holder 8 is engaged with and received within the receiving groove 9 so that the first vertical portion 31 of the grounding apparatus 30 makes contact with the receiving groove 9.

Accordingly, the signal cable 6 is grounded to the bottom chassis 5 through the clamp 24, the second vertical plate 33, the horizontal portion 32 and the first vertical plate 31.

Therefore, the grounding apparatus has the advantage that grounding of the signal cable is carried out at the same time that the signal cable is secured to the bottom chassis.

Furthermore, since tools (such as a screw) are not needed for the assembly process thereof, the manufacturing cost is decreased.

While the present invention has been particularly shown and described with reference to a particular embodiment thereof, it will be understood by those skilled arts that various changes therein may be affected in form without departing from the spirit and scope of the invention as defined by the appended claims.
